There is a fault in the AutoDos.
Check whether the PowerDisk holder and the PowerDisk have been fitted correctly:
The arrows in the PowerDisk holder and in the viewing window must point towards each other.
The holder must lie flat.
The PowerDisk must lie flush with it.
Clean the Miele AutoDos system.
Activate the AutoDos function and restart the programme.
If the fault message appears again, there is a technical fault.
You can continue to use your dishwasher by deactivating automatic dispensing in the Extras menu of a programme and manually dispensing the detergent via the detergent compartment.
If you wish to use automatic dispensing again, contact the Miele Customer Service Department.
